PHY II ESSAY REPORT Wheatstone Bridge and Resistance The 19th century was as very good era of discovery in electrical knowledge, and technology that laid the foundation for what we see today in our society. Scientist like Luigi Galvani for his work with frogs led to his discovery in 1781 of galvanic or voltaic electricity. Galvani found he could make the muscles of a dead frog twitch when he touched them with different metals or the current from a nearby static electric generator. Alessondra

game such as pong or classic breakout. To make breakout you would be using both programs to write the code. A circuit is a path between two or more points along which an electrical current can be carried. An example of a circuit would be a light bulb; a light bulb has a circuit in it which electricity continuously flows to create the light when power is sent to it. An integrated circuit is sometimes called a chip or microchip

I have prepared a report of my investigation into the economic benefits and reliability of common electrical power distribution configurations currently used in the United Kingdom. About 40% of power system investment is in the distribution system equipment (40% in generation, 20% in transmission). Power systems are comprised of 3 basic electrical subsystems. • Generation subsystem • Transmission subsystem • Distribution subsystem We distinguish between these various portions of the power

Objective- The first objective in this lab is to determine how a light bulb behaves in different circuit arrangements. The second objective investigates how the voltage across the light bulb varies with the amount of current through it. Finally, the last objective is to explore how the length of a wire affects resistance. Procedure- Activity 1 A) Measure the voltage across an open-circuit cell by connecting the positive terminal of the voltmeter to the positive terminal of the call and

A lot of people worked to develop the understanding of electricity that we have today. Humanity had to first discover electrical charge to discover electricity. The Greeks were the first to discover electrical charge. Electrical charge is static electricity, or electricity that does not move. This discovery happened over 2,600 years ago. Among those who studied electricity was Benjamin Franklin. He is famous for his experiments with electricity, but he did not discover it. Franklin's famous experiment

loss. The minimum hysteresis loss is achieved by selecting material with small hysteresis loop. Rotor: This is part of the machine which is rotating. Windings in the rotor are known as rotor windings Armature: this the place where the conversion (electrical /mechanical) takes place. In case of synchronous generator this takes place in the stator windings. The stator windings can also be called as armature windings (only for the synchronous generators). The main operation of the motor is based on the

¬¬¬¬¬¬Abstract Electrical circuits are described with mathematical expressions. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current

Bibliography Electrotherapy is a range of beauty treatments that use electrical currents passed through the skin to produce many therapeutic effects. In this report I have researched and written about nine machines and the effects they have on the body. High Frequency. The high frequency machines can be a small table top unit or a large free standing unit, with many of the larger units housing a number of different electrical equipment. Most units have two switches: one on/off and the other to

INFORMATION TECHNOLOGY IN ELECTRICAL ENGINEERING Electrical engineering is one of the newer branches of engineering, and dates back to the late 19th century. It is the branch of engineering that deals with the technology of electricity. Electrical engineers work on a wide range of components, devices and systems, from tiny microchips to huge power station generators. Electrical engineering has now subdivided into a wide range of subfields including electronics, digital computers, power engineering
